GameSpot has put together a preview of NCsoft and Cryptic Studios' upcoming standalone MMORPG expansion, City of Villains. Check it out:

Of course, the one thing that was truly missing from the original City of Heroes was player-versus-player combat. Without an opposing force to fight, it wouldn't have made a lot of sense for heroes to go around beating one another up. Now that the archcriminals will be coming to town, PVP combat shall be fully realized, with heroes and villains able to go up against one another to defend territory and generally just blast the hell out of one another. To that end, villains will be able to take one another on as well, for as we all know, there's no honor among thieves.
